Synchronous Servo Relay

Schwerll Fluid Control Technical Division

SKU: SCH-1016

SCHWERLL’s official product description presents the Synchronous Servo Relay in the context of hydraulic servo digital synchronization. Cited application examples include penstock-gate synchronization in hydropower stations.

At system level, SCHWERLL describes servo-valve tracking and an architecture that may use multi-channel hard-sync cylinders driven by a piston accumulator with energy monitoring to support emergency closing during faults or complete power loss. The final supplied relay, valve, cylinder, accumulator, controller and mechanical arrangement is project-specific and must be confirmed with SCHWERLL.

Frequently Asked Questions

How does the SCHWERLL Synchronous Servo Relay support synchronization during a power loss?

SCHWERLL's official product description explains that its hydraulic servo digital synchronization system can use a piston accumulator with energy monitoring to drive multi-channel hard-sync cylinders, supporting emergency closing and synchronized operation during complete power loss. The exact supplied system configuration should be confirmed for the project.

Where is the SCHWERLL Synchronous Servo Relay used?

SCHWERLL cites applications such as penstock-gate synchronization in hydropower stations, where hydraulic servo digital control is used for high-precision and repeatable synchronized motion. The final relay, valve, cylinder, accumulator and control configuration is project-specific.
